Is the world not full of great work people have done as teams?
If I look around my lounge room right now, literally everything my eyes can see was put together by, not just a team, but a company (literally a team of teams), and much of it is actually very good and has already lasted for many years without fault.
I challenge you to name one person who has built a thing on their own without anyone else’s help.
What's the definition of a good project in your mind? I believe you, and the person you are replying to, are coming at this from two different frames of mind.
Is the quality of the final product all that matters? Is how the people working on the project felt during it a factor?
I'm, for instance, quite happy with the keyboard I am using at the moment. I doubt, very much, that it is the result of the work of a lone individual or a pair. Is your point that the original design might have been drawn by a lone individual, and you view the rest of the work performed by other people as mere augments to that person's vision?
I also did a lot of other projects. Like building engines or houses or planning cities or doing a movie.
Only in software you have the luxury to do it alone or in a pair. In architecture it sometimes works, in movies rarely (but such things do exist, like Shane Carruth), in engineering very rarely. In architecture or movies we call that phenomenon, many cooks don't make good meals. Or planning by committee. Never give up your project to a committee. Eg. Guido or Larry made a huge mistake.
Compared to those other fields and comparing the results you see excellency mostly with projects made by the fewest amount of people.
In SW its trivial to see. All projects managed by a big team are barely successful and more look like managed towards destruction. All managed still by a good founder do look great. Genetic arguments rarely count here.
Clearly NASA's Apollo programme would have been more of a success with only one or two people executing it. Or the Large Hadron Collider. Or the Linux Kernel (and no, that's very much not the work of one person). Or anything else of any real scale or import.
